【摘要】 用偏最小二乘法（ＰＬＳ）校正了火焰原子吸收分析中Ｅｕ３２４．７５３ｎｍ对Ｃｕ３２４．７５４ｎｍ吸收线重叠干扰，用铜空心阴极灯同时测定了合成样及稀土氧化物中的Ｅｕ和Ｃｕ。更多还原

【Abstract】 Partial least squares regression was used to compensate for spectral "overlap" interference of Eu 324 753 nm with Cu 324 754 nm in atomic absorption spectrometry.We could only use the copper element hollow cathode lamp to simultaneous determine Eu and Cu in synthetic samples and rare earth oxide,and obtained satisfactory results.更多还原
